HEAD FOR SHIPPING DRUMS.

Application filed April 16, 1927. SerialNo. 184,256.

This invention relates broadly to metallic shipping drums, and morespecifically to a head and removable cover for such drums.

The primary object of the inventlon is to provide a sheet metal barrelOI" dlllII1-l1k8 container of a type commonly employed for one-time usein shipping heavy materlal, as-

powdered calcium carbide, the same having a head and slip coverconstruction adapted to withstand the usual shocks and jars incident torough handling wlthout rupture at the joints and without danger ofthecover becoming so dislod ed or unseated as to permit leakage, or sifting, of the contents of the barrel.

A further object is to provide a head and cover structure of thecharacter mentioned embodying means whereby much of the force of shocksto which it is subjected 1s e ffectually absorbed without injury to theo nts.

In describing the invention in detall, reference is herein had to theaccompanying drawings,in which Figure 1 is a head-end elevation of adrum embodying my invention;

Figure 2 1s a section on line 2-2, Fig. 13

Figure 3 is an enlarged detail section on line 3-3, Fig. 1.-

Referring to said draw1ngs, 1 designates the body of a drum orbarrel-like contalner of the general character employed 1n makingone-time shipments of materials and ordinarily made of light-gaugesheet. metal. Attached to one end of the body'l in any appropriatemanner, as by the lock-seam 2 shown in the drawings, is a sheetmetalhead 3 having therein'a central opening des gned for the receptionof a removable closure 4 of the slip-cover type, said opening beingdefined by an upwardly extending flange 5 which is designed to' receivethe closure 4 in snugly sea-ted relation thereto.

The flange 5 is constituted by an exten The upper edge portion 5 of theflange 5 is turned outwardly into partially over hanging relation to theupwardly facing channel which is formed by the provision of the bead 6,thereby forming a seat for the reception of a gasket 8.

The closure or coverv i has an upright annular Wall 9 which seats snuglywithin the embrace of the head flange 5 and which has its upper edgeportion or extremity curved outward to form a roll-like terminal 9 forseating upon the seated gasket 8. Tongues 10 are formed at suitablyspaced intervals on the edge 5* of the flange 5, the same being adaptedto be bent inward into seated relation to the terminal roll 9 forsecuring the cover in its properly seated position in compressingrelation to the interposed gasket.

Formed in the head 3 directly adjacent to the seam 2 is an upwardlypressed bead 11 which is designed to render the head yield able relativeto the seam under shocks to which the container is subjected, thereby toterminal IOll thereof acts to compress the gasket into sealing relationto the joint between said cover and the head 3. Moreover, it will beapparent that the flangefi and the'therewith associated double, orreverse, bead formation of the head provide an especially resilientconstruction'adaptcd to absorb impacts or shocks incident to forcibleshifting of the contents of the drum against the head and cover whichwould otherwise tend either to rupture the head or to so distort thelatter as to permit leakage at the joint.

What is claimed is 1. A sheet me-tal'cont-aine-r having a head formedwith a central circular opening de-' fined by an upstanding flange, saidhead having therein a downwardly pressed bead of'whichthe inner wall isextended to form said flange, said head also having therein an brace ofsaid flange, and tongues formed on said flange for bending inwardly intoretaining relation to said cover.

2. A sheet metal container having a head formed with a central circularopening defined by an upstanding flange, said head having therein adownwardly pressed bead of which the inner wall is extended to form saidflange, said flange having its terminal edge portion turned outwardlyinto overhanging relation to said bead to form a seat for a gasket, saidhead also having therein an upwardly pressed bead disposed in closelyencircling relation to the," downwardly pressed bead, a slip coverhaving an upright annular flange for seating within the em brace of saidhead flange and provided with a terminal edge portion turned outwardlyinto overhanging relation to said gasket seat, and tongues formed onsaid head flange adapted to be turned inwardly into seated relation tosaid terminal edge portion of the cover flange, the reversely disposedbeads cooperating to render that portion of the head adjacentto thecover readily resilient for absorbing impacts and preventing rupture ofthe joint between the head flange and the cover.

3. A sheet metal container comprising a body, a head attachedperipherally to said body and having therein a central circular opening,an upstanding flange defining said opening and having its terminal edgeportion inclined outward to form a gasket seat, tongues borne by saidedge port-ion at spaced intervals, said head having therein a downwardlypressed circular bead and a closely adjacent encircling upwardly pressedbead, the inner wall of the downwardly pressed bead having said flangeformed as a continuation thereof, and the adjacent walls of said beadscombining to form a compound curvature, and a removable slip coverfitted within said opening, said cover having an upright flange receivedsnugly within the embrace of said head flange and terminating in anoutwardly turned portion which overhangs said gasket seat, said tonguesbeing adapted for turning into seated relation to said outwardly turnedport-ion of the cover flange.

4. A sheet metal container comprising a body, a head attached to saidbody through the provision of a seam, said head having an upwardlypressed bead formed therein closely adjacent to said seam, said headbeing provided with a circular opening defined by an upstanding flangeand having therein a downwardly pressed bead of which the inner wall isextended to form said flange, said flange having its terminal edgeportion inclined outwardly to form a seat for a gasket, a slip coverhaving an upright annular flange fitted within the embrace of c saidhead flange and provided with a terminal portion which overhangs saidseatfor resting upon a gasket supported by the latter, and means wherebysaid cover is se-i cured in its seated closing position.

5. A sheet metalcontainer comprising a body, ahead attached to said bodythrough the provision of a seam, said head having' an upwardly pressedbead formed therein closely adjacent to said seam, said head beingprovided with a circular opening defined by an upstanding flange andhaving therein a downwardly pressed bead of which the inner wall isextended to form said flange, said flange having its terminal edgeportion inclined outwardly to form a seat for a gasket, a slip coverhaving an upright annular flange fitted Within the embrace of said headflange and provided with a terminal portion which overhangs said seatfor resting upon a gasket borne by said seat, and a plurality of tonguesformed upon said terminal edge portion of the head flange and adaptedfor turning into overlying seated relation to the terminal portion ofsaid cover flange. In testimony whereof, ll affix my signature. 7
